How Transit Testing Saves You from High Returns and Damage Rates

Experienced supply chain practitioners understand the types of damage that may occur to a package and the root causes of this damage. Although some amount of stress may be unavoidable, proactive planning and testing can minimize the amount of damage that occurs to packages during transit. 

Packages endure multiple sources of stress during shipment. Designing packaging that can withstand the unintentional stress that will occur, despite the best intentions of handlers, throughout the supply chain is a challenging task. Experienced supply chain practitioners understand the types of damage that may occur to a package and the root causes of this damage. Although some amount of stress may be unavoidable, proactive planning and testing can minimize the amount of damage that occurs to packages during transit. 

 

Understanding the specific journey of each product through a complicated supply chain allows supply chain planners to anticipate potential sources of damage. Proactively designing packaging that can withstand harsh transit conditions helps reduce

damaged packages and subsequent product returns.

 

Transit testing is designed to simulate the shipment conditions for all of the packaging that surrounds the product. This includes the product package, the carton, and the master outer carton (MOC). Conceptually, transit testing is designed to proactively mitigate any harm that might occur during transit to any of these packages. Although transit testing is designed to protect each of these packages, the product package (or retail package) is the primary package that the consumer sees. 

Packaging Influences Brand Perception

Each touchpoint a consumer has with a brand influences the consumer’s perception of that brand. For brick and mortar retail, the consumer will first interact with the product package, that encases the product, before touching the product. For ecommerce, the consumer may also interact with the corrugated carton that is used to ship the product package direct to the consumer.    

 

Brands have a vested interest in making sure that packages arrive to consumers intact and that the products contained in the package will work as intended. When a consumer receives an intact package, they are subtly assured that their product was protected during transit and assume the product is in good working order. However, if a consumer receives a damaged package, they may have immediate concerns regarding whether the damage done to the package has also caused damage to the product contained in the package. This may cause the consumer to become concerned regarding how the product will function – not just whether it will work as intended in the short-term, but also whether any damage occurred that may impact the product’s long-term performance.    

 

Master Outer Cartons (MOCs) protect cartons as they travel from the factory to the Distribution Center (DC). Designing MOCs to withstand the rigours of their journey to the DC helps ensure that both the carton and the product package that ship to the customer will be unblemished when they leave the DC center.   

 

What are the Transit Conditions that Might Damage Your Product?

 

Damage may occur to your product as a result of transit, package handling, or damage that occurs during storage.  

Transit Damage

Products may get damaged while the product travels from one location to another location. This type of damage may include:

  • Moisture
  • Cold
  • Intense Heat
  • Sudden movements
  • Vibrations
  • Accelerations
  • Decelerations
  • Hard breaking
  • Sharp turns
  • Seaspray
  • Rain
    • Products that are left outside for staging while in queue for loading for ocean or air freight
  • Container rain
    • Accumulated condensation within a sea container that drops onto the cargo

Package Handling Damage

Package handling, whether caused by a person or an automated handling system, may include damage caused by: 

  • Hard shocks
  • Scratches
  • Drops
  • Falling off a conveyor belt
  • Falling off a truck
  • An entire container falling into the ocean

Warehouse Damage

The environment that a package is stored in can impact package integrity. Environmental factors that could adversely affect packages include: 

  • Compression from stacking
  • Dust and/or sand
  • Unstable shelving units
  • Forklift damage - punctures or misaligned pallet stacking

Map Out Your Product's Unique Journey to Market

The transit journey of each product is unique. One product may have multiple transit journeys. Sometimes an individual product is sold through multiple channels, like retail and ecommerce. Likewise, one product may travel to multiple geographical locations.  

 

For example, a product may be manufactured in Southeast Asia (SEA) and then be transported by ship to the United States where it will then travel by train to a DC. From the DC, the package may travel by truck to be delivered to a retail store or directly to the customer's doorstep. 

It is important to be quite thorough when mapping out your product’s journey. In order to design effective tests, the test designer needs to understand all of the conditions that your product will be subjected to during its journey. 

Define the Test Objective

Each pre-transit test is customized to the unique journey that your product will take. 

 

Based on the conditions your product will undergo during its journey, you should carefully define the test objective. In the International Safe Transit Association’s (ISTA’s) guide, Getting Started with Design & Testing , example test objectives are explained. Examples of test objectives include: 

  • Screening tests are designed to avoid serious product damage during shipment.
  • Prediction testing is more subtle. These tests require test designers to anticipate sources of minor or intermittent damage.  

Organizationally, you should decide who, internally, will determine the test objectives. Once the test objectives have been established, you need to be sure to obtain organizational buy-in from everyone on your internal team who will be impacted by what happens to the product during transit.  


Standards Organisations Provide a Framework for Developing Pre-Transit Testing

ISTA “is a member-based nonprofit that empowers organizations, and their people, to minimize product damage throughout distribution and optimize resource usage through effective package design”.  ISTA provides testing frameworks for various conditions that products may experience during shipment. A list of their testing frameworks follow: 

  • Non-simulation integrity tests
  • Partial simulation tests
  • General simulation tests
  • Enhanced simulation tests
  • Member performance
  • Development tests
  • Data depot
Our testing lab in Shenzhen is equipped to handle many of the ISTA tests to ensure the packaging we design can withstand the demands of an international supply chain.

Designing a testing framework that precisely matches your product’s journey is a process that requires experience. Some transit routes may require a more nuanced understanding in order to accurately anticipate what conditions a product may encounter during transit. 

 

The impact of rain on air cargo is one example of potential packaging challenges during transit. For example, if an MOC sits on a tarmac during a downpour, then the MOC may become saturated with rainwater. This can result in the MOC becoming compromised which can potentially cause product damage.   

 

For example, an apparel manufacturing company that was expediting shipments via air freight experienced product damage when their product sat on the tarmac during adverse weather conditions for an extended period of time. The packages became saturated during a downpour. As the packaging was not designed to be water resistant, the packaging failed to protect the apparel from the rain. Consequently the product was significantly damaged.


How Do You Make Sure Your Test is Designed to Current Industry Standards?


Standards organizations frequently update their standards. When selecting which tests are appropriate for your pre-transit testing, make sure that you are designing and testing your packaging to meet the most recent set of standards.


If you use a third-party lab to execute a test that you have designed, be sure the lab has up-to-date laboratory certification.
It is a good idea to document your tests so that somebody who is not knowledgeable about the test can understand the test design and execution. If you are testing for ISTA compliance, you should refer to their specific testing documentation requirements.
Experienced Packaging Solution Providers can provide testing services to monitor retail packages in cartons to document force to the product during drop impacts or vibration testing. These Packaging Solution Providers can generate reports to support validation tests.


You should also determine whether you have internal and external reporting structures that require proof that you have done pre-transit testing. If so, do you have resources available that can accurately meet the documentation requirements?


What is the Difference Between Testing the Integrity of an Individual Package and Conducting a Pilot Test?


In the laboratory, tests can be conducted to test for specific types of package failures for particular package designs. The below chart summarizes some typical tests:

 

For smaller scale tests, a few packages may be shipped, on an individual basis, to known destinations where an internal team member can perform an inspection on the package and determine whether the package was able to adequately withstand the stress of the journey.

 

A pilot test includes a more comprehensive simulation of what multiple packages endure during transit. With an increased number of packages shipped, additional data points are available to determine how well the packaging has held up as it travels to multiple destinations.  

Define Acceptable Tolerances for Product Damage and Packaging Degradation

In an ideal world, each and every product would arrive at its destination intact with no damage to the packaging. Pragmatically, this can be a difficult and expensive goal to achieve.

 

Your organization should define how much damage it is willing to tolerate both to the product and to the package. Packaging World categorizes this concept as Product Damage Tolerance (PDT) and Package Degradation Allowance (PDA). PDT refers to defining how much damage you might be willing to accept on your delivered product. For example, you may define that the product needs to arrive fully functional, but small aesthetic damages, like tiny scratches on the bottom of a product may be allowed. Typically, “tiny” would be defined with specific length and width dimensions to clarify the acceptable size of a scratch. PDA definitions may include whether small punctures to the outside shipping carton are allowed and whether the carton sealing method needs to remain completely intact.

 

An additional consideration is that packaging has a shelf life. Packaging is designed and tested based on how long the product will be stored either in a warehouse or on a store shelf. Package design should also include the shipping and handling criteria that is needed to protect the product and ensure that packaging degradation is avoided.

 

Each brand needs to determine product damage tolerances for their products. If product damage occurs during testing, damage can be discussed after testing is concluded. In some instances, minor damage may be acceptable. Significant damage would require packaging redesign.

 

Design the Packaging for the Harshest Conditions the Product Will Endure During Shipment

 

One product, defined as an individual SKU, may be sold through different channels. For example, a blue standard sized flashlight may be sold through ecommerce or through brick and mortar retail. This blue flashlight may be manufactured in SEA and distributed globally. Ambient temperature conditions on vessels, container trucks, DCs, warehouses, and last mile of delivery vehicles will vary based on weather conditions in various geographies.  

 

In certain parts of the world, the package may be subjected to a harsher transit journey than in other parts of the world. Variability in the harshness of a journey may be caused by environmental, economic, workforce sophistication (including the education levels of workers) or any other assortment of factors. To simplify order fulfillment requirements, manufacturers are motivated to package each individual SKU identically. When each product is interchangeable with each other, order fulfillment is simplified. (Whether the blue flashlight will be sent to hot, sandy Egypt or cold, snowy Alaska, the packaging of the blue flashlight will be identical.) In some instances, this may cause a product shipped via the least harsh supply chain to appear “overpackaged” when, in reality, the packaging was designed to withstand the rigours of the harshest supply chain the product travels through. Creating a singular package design that is suitable for disparate retail environments and differing transit routes can be quite challenging.

Benefits of Successful Pre-Transit Testing

Brands typically have the goal that customers should have a pleasant and gratifying experience when they receive a new product. Properly designed packaging, that can withstand transit stresses and arrive, unblemished, at the customer destination is the goal of packaging designers.

 

When pristine packages arrive at a customer location, brand integrity is preserved and expensive returns are prevented.
